Definitions
- the invention relates to an electrical Switches for a motor vehicle, in particular Steering wheel switch, with a manual actuator to carry out at least one switching operation of a structural unit, which are connected to the switch via a control unit is.
- control unit is coupled to a steering angle sensor and depending on at least one Rotational position of a steering wheel releases the switching process or locks.
- the control unit evaluates the signal from the steering angle sensor regarding the angular position of the steering wheel out. With an angle of rotation position, that of driving straight ahead corresponds to the motor vehicle, gives the control unit the switching operations usually assigned to the switch free. After approval, for example any settings of the car radio, the air conditioning or the vehicle speed control by Actuate the switch. To e.g. at a Accidentally incorrect operation of the motor vehicle when cornering of the switch, for example an unwanted Adjustment of the radio or the cruise control has the result of reliably excluding the control unit blocks the by pressing the Switch initiated switching operation. It is possible the switch relatively close to the operator's hand, i.e. in the immediate vicinity of the steering wheel rim arrange in the steering wheel spokes, as the accidental Incorrect operation of the switch due to the interaction of the control unit with the steering angle sensor excluded is. This also allows an ergonomic Arrange the switch.
- the task according to the invention solved that the control unit with a steering angle sensor is coupled and depending on the rotational movement the steering wheel releases the switching process or locks.
- the control unit preferably gives in dependence from the rotation of the steering wheel the switching process freely or blocks the switching process. This is the release or blocking the by pressing the switch triggered switching process depending on whether the steering wheel moves when the switch is actuated will or not. With an essentially static Turning position of the steering wheel, e.g. when passing one long curve, the control unit gives all switching operations free.
- the control unit can also control the speed, with which the steering wheel is turned, due to the time signal sequence of the steering angle sensor consider.
- Control unit for example, a switching operation that a switched on cruise control Reduce speed or shutdown Cruise control results in being free while there is a gear shift that increases speed causes the motor vehicle, locks.
- the parameters, according to which the control unit works are with the Vehicle production freely programmable.
- the control unit assigns the control unit to several temporally short consecutive different Rotational positions or rotary movements of the steering wheel Switch an alternative switching function.
- the switch that is normally used to set radio functions serves the switching function to trigger a Horn assigned.
- This measure is particularly advantageous if several switches are integrated in one steering wheel are and the control unit or the control units all Switches, for example, a safety-relevant one Assigns switching function since the user does not then search for a specific switch for this switching function must but act on any switch can.
- the control unit advantageously arranges everyone A tolerance range in which there is a releases certain switching operation. So that's what happens Locking a switching process is not already at a relative small change in the rotational position, but only then, if the changed rotary position is outside the specified Tolerance range. So there are minor corrections the direction of travel while maintaining the switching function ensured.
- the steering wheel 1 When driving the motor vehicle straight ahead the steering wheel 1 assumes a certain rotational position, the detected by the steering angle sensor and by the control units 9, 10 is evaluated. In this rotary position of the Steering wheel 1 are all assigned to switches 5 Switching functions released by the control units 9, 10.
- the on-board computer 11 is for displaying information on the display device 12 within the scope of the predetermined Selection menus can be controlled as required and the vehicle speed control can be switched on and off and with the cruise control switched on can by the speed of the motor vehicle an exposure to the corresponding switch 5 increases or be slowed down. If the steering wheel 1 is rotated, there is the risk of incorrect operation of the switch 5 accidental actuation of the actuators 4 the switch 5 when handling the steering wheel.
- the control units evaluate preventing such incorrect operation 9, 10 the signals from the steering angle sensor, register a rotation of the steering wheel 1 into a rotational position, which corresponds to cornering of the motor vehicle, and block the switches 5 associated switching operations. So, for example, there is an increase in speed by an accidental application of the corresponding switch 5 prevented. Against it a switching process for switching off the cruise control even during cornering of the motor vehicle Approved.
